I am looking for a Ryobi weed eater manual. Need to know how much oil to put in my weed eater. Can you give me an answer or where I can get a free manual. Thanks

U sure about that? Never come across a weed eater that was not of the bump kind!

On internet go to www.manuals.ryobitools.com and search for 790r. Next scroll down the page looking for the trilingual manual. Download the PDF version and you will have it quickly.

I work with weed eaters and mowers. Weed eater fuel ratio is normally a 40:1 ratio. That usually all weed eaters fuel ratio.

Hi jo6616...

Use a good grade of 10W30 non-detergent oil in your weedeater.

Sounds like the clutch has taken a long trip south. If the clutch pads are not wore out, try some wd40 on the pad hinges.

You only need to mix oil with gas when it is a 2 cycle engine. 4 cycle engines run on straight gas. Since you didn't post your model number, here is a site you can hopefully find your owners manual at. Hope this helps.

Unless it has a tag or decal on it saying it is a 4 cycle then it uses mixed gas/oil at about a 50:1 ratio. Straight gasoline will freeze the piston in the cylinder in mere minutes.
